Reaction: an α-sulfoquinovosyl diacylglycerol + H2O = sulfoquinovose + a 1,2-diacylglycerol
Glossary: quinovose = 6-deoxy-D-glucopyranose
Other name(s): yihQ (gene name)
Systematic name: α-sulfoquinovosyl diacylglycerol sulfoquinovohydrolase
Comments: The enzyme, characterized from the bacteria Escherichia coli and Pseudomonas putida, hydrolyses terminal non-reducing α-sulfoquinovoside residues in α-sulfoquinovosyl diacylglycerides and α-sulfoquinovosyl glycerol.
